The increasing range of Aedes aegypti, vector for Zika, dengue, chikungunya, and other viruses, has brought attention to the need to understand the population and transmission dynamics of this mosquito. It is well understood that environmental factors and breeding site characteristics play a role in organismal development and the potential to transmit pathogens. In this study, we observe the im...

1 The emergence pattern of Thanasimus dubius (F.) (Coleoptera: Cleridae), a common predator of the southern pine beetle, Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae), was studied under ®eld conditions across different seasons. A simple statistical model was then developed to characterize the emergence data, using the truncated geometric distribution. Data are also presented on the...

Some patients with intellectual disabilities spend longer than others in emergence from ambulatory general anesthesia for dental treatment. Although antiepileptic drugs and anesthetics might be involved, an independent predictor for delay of the emergence remains unclear. Thus, a purpose of this study is to identify independent factors affecting the delay of emergence from general anesthesia. T...

Although circadian clocks are believed to have evolved under the action of periodic selection pressures (selection on phasing) present in the geophysical environment, there is very little rigorous and systematic empirical evidence to support this. In the present study, we examined the effect of selection for adult emergence in a narrow window of time on the circadian rhythms of fruit flies Dros...

BACKGROUND Desflurane with a laryngeal mask airway may have advantages during ambulatory anesthesia. However, desflurane-induced airway irritability makes the use of desflurane challenging, especially in children. This study compared desflurane with sevoflurane maintenance anesthesia in terms of respiratory events and the emergence characteristics in children with a laryngeal mask airway. MET...

Magnetic resonance imaging (MRI) is a widely applied diagnostic approach for detection of pediatric diseases. Sedatives are commonly used to acquire the accurate MRI images. Dexmedetomidine and propofol serve as sole or combined sedatives in pediatric MRI scanning. This meta-analysis aimed to compare the efficacy of dexmedetomidine and propofol in children ubdergoing MRI. Pubmed, Cochrane Libra...

Background and aim: The third stage of labour is one of the most troublesome stages of child delivery. The basic principle of the third stage management is administrating prophylactic uterotonics. However, the time of its administration varies in different hospitals. This study aimed to determine the effect of intramuscular oxytocin injection after emergence of the fetal anterior shoulder or pl...

BACKGROUND Little is known about ageing-related changes in the brain that affect emergence from general anaesthesia. We used young adult and aged Fischer 344 rats to test the hypothesis that ageing delays emergence from general anaesthesia by increasing anaesthetic sensitivity in the brain. METHODS Time to emergence was determined for isoflurane (1.5 vol% for 45 min) and propofol (8 mg kg(-1)...

BACKGROUND A recent study showed that methylphenidate induces emergence from isoflurane anesthesia. Methylphenidate inhibits dopamine and norepinephrine reuptake transporters. The objective of this study was to test the hypothesis that selective dopamine receptor activation induces emergence from isoflurane anesthesia. METHODS In adult rats, we tested the effects of chloro-APB (D1 agonist) an...
